[Circulatory changes in acute sauna hyperthermia after heart transplantation].

The authors report on the influence of a single sauna-stay of patients following heart transplantation (HTX) during the rehabilitation phase III. Investigations of blood pressure, heart rate, changer in hemodynamics in the small and large vessels in 8 male patients following HTX (medium age: 42 years) showed that sauna-hyperthermia is well tolerated. We watched significant decreases of blood pressure (systolic and diastolic values), an improvement of the microcirculation in the small vessels, an increase of the left ventricular ejection fraction (LVEF) and a decrease of the total peripheric vascular resistance (TPVR). Possibilities and limitations of sauna-therapy for the therapy of risk factors following HTX especially under immunosuppression are discussed. First results are demonstrated.
